We propose and analyze a general periodic-review model in which the firm has access to a set of potential suppliers, each with specific yield and price characteristics. Assuming that unsatisfied demand is backlogged, the firm incurs three types of costs: (i) procurement costs, (ii) inventory-carrying costs for units carried over from one period to the next, and (iii) backlogging costs.
We propose a model of asset management in which benchmarking arises endogenously, and analyze its unintended welfare consequences. Fund managers' portfolios are unobservable and they incur private costs in running them. Conditioning managers' compensation on a benchmark portfolio's performance partially protects them from risk, and thus boosts their incentives to invest in risky assets. In general equilibrium, these compensation contracts create an externality through their effect on asset prices.
I develop a model of group decision-making, in which a committee generates proposals and holds open discussions, but the ultimate decision is either taken by a leader (decision by authority) or by majority vote. Optimal communication processes are studied that combine both cheap talk statements (proposals) and costly state verification (discussions). I show that by favouring one particular agent—the leader—authoritative decisionmaking reduces rent-seeking discussions and often results in a higher decision-quality relative to majority decision-making.
Until fairly recently, the main approach to getting business to respond to climate change has been top-down efforts to regulate emissions and enact various forms of "carbon pricing." The aim of such efforts has been to make businesses "internalize" the costs associated with greenhouse gas (GHG) emissions. Governments are expected to set the environmental protection rules for companies in their respective countries, and markets are expected to adjust to the new regulations and carbon prices.
